Hello,
We are using the XS9922B chip to convert data from four AHD cameras into MIPI CSI2 signals, which are then connected to the NVIDIA CSI interface.
We have completed the device tree and driver development, successfully testing video signals and achieving stable operation (1920x1080 at 25fps, with test video).
However, when we connect the actual AHD camera signal, we encounter an issue where the system cannot operate for long. After a few seconds to over a minute of video input, the image exhibits partial corruption, and errors are reported, causing the video stream to stop displaying. Restarting the gstreamer pipeline continues to result in the same issue. We would appreciate any advice to help us diagnose the problem.
Specific steps and observations are as follows:
1. System Version
uname -a
Linux ubuntu 5.10.120-tegra #3 SMP PREEMPT Thu Sep 19 21:32:22 CST 2024 aarch64 aarch64 aarch64 GNU/Linux
cat /etc/nv_tegra_release
# R35 (release), REVISION: 4.1, GCID: 33958178, BOARD: t186ref, EABI: aarch64, DATE: Tue Aug 1 19:57:35 UTC 2023
2.Using GStreamer to Open the Device Without Connecting the AHD Camera (Outputting Test Video)
gst-launch-1.0 -v v4l2src device="/dev/video4" ! video/x-raw,framerate=30/1,width=1920,height=1080,format=UYVY ! xvimagesink &
We can see that it outputs the color test image normally. However, we also noticed an error: CHANSEL_NOMATCH.
Trace output:

3.Using GStreamer to Open the Device with AHD Camera Connected
Initially, we can receive data from the AHD camera. However, after a few seconds to over a minute, the image shows corruption, and we can observe corresponding errors in dmesg and trace_pipe.
Live dmesg output:
[16771.638938] --------cntt= 24-----
[16778.425426] tegra-camrtc-capture-vi tegra-capture-vi: corr_err: discarding frame 0, flags: 0, err_data 512

[16778.542079] tegra-camrtc-capture-vi tegra-capture-vi: corr_err: discarding frame 0, flags: 0, err_data 512
We can see that after seven seconds of capturing, there is a screen distortion phenomenon, and image capture cannot continue.

In the trace_pipe log, we saw the following errors:
rtcpu_nvcsi_intr : class:CORRECTABLE_ERR : status : 0x00000004
rtcpu_vinotify_error : tag : CHANSEL_NOMATCH
rtcpu_vinotify_error: tag : CSIMUX_FRAME
tcpu_nvcsi_intr : class:GLOBAL type:STREAM_VC : status:0x00000008
Therefore, we would like to ask what could be the cause of these errors. Is it due to incorrect device tree properties, incomplete MIPI signals, or perhaps we should consider making a new camera board? We look forward to your reply.
